What captures the promise of a fixed pension level based on earnings and seniority?

The correct choice is a defined-benefit plan, which captures the promise of a fixed pension level based on earnings and seniority. This type of plan guarantees a specific retirement benefit amount, which is typically calculated using a formula that considers the employee's salary history, duration of employment, and potentially other factors such as age at retirement.

Defined-benefit plans provide financial predictability for employees as they can anticipate their retirement income based on the established formula. This helps employees plan their finances for retirement effectively, as they are assured of receiving a stable income throughout their retirement years.

In contrast, defined-contribution plans do not promise a specific benefit at retirement; instead, they rely on contributions made to the plan and investment performance. Incentive programs generally focus on performance-based rewards rather than retirement benefits. Health benefits are related to medical coverage and do not involve fixed pension levels. The focus of a defined-benefit plan distinctly illustrates the commitment to providing a predetermined level of retirement income based on an individual's earnings and length of service.
